The paper deals with tracking problem for single-input single-output linear systems with unstable zero dynamics under parametric and signal uncertainty of control plant and reference model within the framework of the sliding mode techniques for feedback design, state observation and parameters identification in real time. 1 This work was supported in part by the Russian Foundation for Basic Res...

A group of multi-input-single-output fuzzy logic controllers are designed for a nuclear power plant to control turbine power, reactor pressure, and reactor water level based on input-output data from plant simulations with conventional PI controllers. Simulations show that fuzzy logic control may result in faster reference signal tracking and final value holding. Milder control actions of fuzzy...

In this note, the problem of random reference tracking by linear feedback systems is addressed. The approach is based on the so-called random sensitivity function, which plays the same role as the usual sensitivity function in step reference tracking. Using the random sensitivity function, quality indicators for random reference tracking are introduced, and their utilization for analysis and de...

In this paper, we consider uncertain=nonlinear systems subject to unknown constant disturbance inputs. We wish to design state feedback controllers which ensure that the system output asymptotically tracks a speci3ed constant reference signal and all states are bounded. The controllers we consider are PI in the sense that they consist of a piece which depends linearly on the state and another p...

In this paper, in order to control uncertain chaotic system, an adaptive fuzzy control(AFC) scheme is developed for the multi-input/multi-output plants represented by the Takagi-Sugeno(T-S) fuzzy models. The proposed AFC scheme provides robust tracking of a desired signal for the T-S fuzzy systems with uncertain parameters. The developed control law and adaptive law guarantee the boundedness of...

PI controllers are designed to track constant reference outputs while rejecting constant disturbances. We consider this controller structure for tracking problems where disturbance and reference signals have bounded derivatives. It is shown that tracking can be achieved with a bound on the tracking error which is determined by the bound on the derivatives of disturbance and reference signals. I...

Solution to the safe and collision-free trajectory of the wheeled mobile robot in cluttered environments containing the static and/or dynamic obstacle has become a very popular and challenging research topic in the last decade. Notwithstanding of the amount of publications dealing with the different aspects of this field, the ongoing efforts to address the more effective and creative methods is...

Maximum power point tracking controller is essential to obtain the maximum power from a solar array in the photovoltaic systems as the PV power module varies with the temperature and solar irradiation. In this paper, several methods for the MPPT of the PV systems are discussed and it can to be used as a Helpful reference for the upcoming MPPT user in the PV applications.

This paper studies an enhanced dual-stage repetitive controller (RC) for improved robustness and tracking of periodic reference trajectories in piezo-based nanopositioning systems. The dual-stage RC system consists of a signal generator designed to provide high gain at the fundamental and all the harmonic frequencies of the reference trajectory and another that offers high gain only at the odd ...
